java - Delimiter to use for parsing negative numbers -

-

मैं integers (सकारात्मक और नकारात्मक) को खोजने के लिए split का उपयोग कर एक स्ट्रिंग पार्स करना चाहता हूं। उदाहरण के लिए, dfgs # & amp; -6d5।, B-dgj895-9-8 सरणी में बदल जाएगा [- 6, 5, 895, -9, -8] ।

अंग्रेजी में, regex होगा:

  1. अक्षर जो अंक नहीं हैं
  2. वर्ण जो अंकों के बाद डैश नहीं हैं
  3. ज़ीरो-चौथाई वर्ण जो एक डैश द्वारा पीछा किए जाते हैं, जो एक अंक के बाद होता है

ये अलग घटक हैं, लेकिन मुझे नहीं पता कि उन्हें कैसे एक साथ जुड़ना है:

  1. \ D +
  2. [^ - (? = [0- 9])]
  3. (? = - [0- 9] +)

< P> split स्पष्ट रूप से आप चाहते हैं परिणाम प्राप्त करने के लिए उपयुक्त उपकरण नहीं है हालांकि इसे split के साथ करने के लिए आप इस पद्धति का उपयोग कर सकते हैं: 

  स्ट्रिंग [] nbs = text.split ("(? & Gt; [^ - 0-9] (?! [0-9]) - | +) + | (= - [0-9]) ");

लेकिन आपको खाली परिणाम निकालने की आवश्यकता है (जो शुरुआत के समय या अंत में, स्ट्रिंग के आधार पर हो सकता है)।
